Gilberthorpe says he witnessed two senior Conservatives members of parliament having sex with the boys.

Gilberthorpe says that in 1981 he saw Sir Michael Havers at a swimming pool party at the Conservative conference in Blackpool, where underage boys were encouraged to perform sex acts on several politicians.

Gilberthorpe says : "In 1981 I was invited back to the Imperial Hotel by a ­Conservative councillor.

"He was a big player in the notorious right-wing group the Monday Club.

"We arrived at around midnight and I was led down some stairs to a door where two men were stood as security.

"We were allowed to enter and I was led through a tiled changing room where there were piles of clothes strewn across the floor. We then walked into an area where there was a large pool and lots of men either stood around naked or simply wrapped in towels.

"Among the MPs I recognised in there were Keith Joseph and Rhodes Boyson. I saw the Attorney General Michael Havers down there as well.

"There were a couple of glass tables set up as a mini bar with bottles of spirits on them and there was cocaine on several tables.

"I saw several boys who were clearly aged between 15 and 16 down there and I saw that a few were performing sex acts on MPs."

Gilberthorpe and Thatcher. Thatcher was a very close friend of Sir Jimmy Savile.

Gilberthorpe says he attended a sex party at the Grand Hotel in Brighton during the Conservatives’ 1984 conference.

On the night before the bomb attack, he saw senior MPs engaging in sex acts with boys below the age of consent at a 'corridor party' held in a row of rooms on the fourth floor.

He says: "There were several men walking from one room to another and enjoying sex acts with other naked men, including boys who were clearly only about 15 or 16 years old. I saw Keith Joseph there and a politician who is now still a serving MP.

"It was held on the night before the bomb went off and afterwards one MP crudely joked that it was a good job it was, or there would have been rent boys falling through the floor."

"It was alleged at the time by Scallywag magazine that Stephen Milligan was originally approached by the security services to attempt to dissuade a well-known footballer ... from continuing to hawk his story of gay sex sessions with two then serving cabinet ministers around Fleet Street.

"Milligan was a well respected MP and part time journalist. Milligan allegedly approached the footballer who was not prepared to drop his attempts to sell the story.

"Milligan allegedly reported back to the security services who informed Milligan that unless the footballer did keep matters quiet he would be eliminated.

"Apparently there was more to the story than simply the gay sex aspect, the introduction of the footballer to the cabinet ministers was allegedly arranged by a third party who had very close links with an extremely powerful paedophile ring.

Gaza July 2014. How do Israel and its friends manage to control most of the UK's Members of Parliament? Blackmail over child abuse?

"The implication was that the cabinet ministers may also have been involved with the paedophile ring although this was not confirmed in the Scallywag report, however it was very clearly hinted at...

"The cabinet ministers involved were very high profile indeed and the alleged paedophile link, if revealed, would have had a catastrophic effect on not only public confidence in domestic government but would have had repercussions on the image of Britain right around the world...

"Milligan was allegedly informed by the security services that, his efforts at dissuasion having failed, the footballer would be killed with his death being made to look like an accident.

"Milligan then allegedly threatened the security services that, if anything happened, he would tell the whole story to The Sunday Times.

In the 1980s, Sir Geoffrey Howe had his trousers stolen while travelling on a sleeper train.

Sir Peter Morrison - at the heart of the Thatcher government. A former resident of the Bryn Estyn children's home has told Channel 4 News that he saw Sir Peter Morrison at the notorious care home five times. Eyewitness 'saw Thatcher aide take boys to abuse'. Morrison, who died in 1995, was Margaret Thatcher's parliamentary private secretary.

Meanwhile, we learn that the BBC reporter Daniel Foggo, whose Panorama programme attempted to smear certain child abuse whistleblowers, grew up on same London street as Sir Peter Morrison.

Derek Laud, who is gay, became the first and only black master of foxhounds when he took that role with New Forest Foxhounds in 1999. Derek Laud with Anne (left) and Cicely Meehan, the spinster sisters who gave Derek Laud a home. Cicely Meehan was a child psychologist. One Saturday, Anne drove young Derek to the house of 'a very grand lady ... who bore a striking resemblance to Mrs Thatcher'. Derek Laud is a long standing family friend of Samantha Cameron's family and a personal friend of David Cameron and attended their wedding at Ginge, in Oxfordshire.

2. "Young boys in care were systematically raped and abused by Mr X (JOHN ALLEN) and many other influential people ... children as young as four were schooled in the art of male prostitution."

(Reportedly the child brothels and abuse rings were organised by the security services)

3."Luxury flats in London, Brighton and elsewhere ... were high class homosexual brothels, where Mr X kept, on a permanent basis, rent boys to cater for his VIP clients.

"Regular visitors included ... Lord McAlpine ... the late Lord Kenyon, former chairman of the North Wales Police Authority, Wyn Roberts, MP for Conwy ... Adam Mars-Jones, son of Mr Justice Jones ... six police officers, among them a former superintendent and prominent freemason in Clywd, Gordon Angelsea..."

4.(There is a) "connection between the paedophile ring and close friends of (former cabinet ministers) Michael Portillo and Peter Lilley."

"Paedophile material produced by one of Mr X's companies in Amsterdam (has been traced) to an address in Dolphin Square."

5."It was almost inconceivably evil, to take little boys in care homes owned by Mr X such as 34 Inverness Terrace, Baywater, which has since closed down, or from homes in Castle Road and Finchley Place in London, and subject these children to systematic abuse over a period of years...

"Mr X also financially maintained numerous boys, at houses in Edgeware Road, London, Chester Road, Manchester, Nevinson Avenue, SouthShields, Queens Park, Wrexham, Rock Street Brighton, and so on. All these addresses were used by wealthy paedophiles for sex for cash.

6."Mr X also had a ready supply of boys to use in his burgeoning film business, through a company owned by his niece in Copenhagen.

"Paedophile material was transported to London for private showings in Dolphin Square and nearby Winchester Street, Pimlico, where Derek Laud, Michael Brown MP's boyfriend, had set up home.

"A source in Dolphin square told us: 'We often have underage boys wandering the corridors, totally lost, asking for the flat of a particular MP'...

"'David Steel, who has an apartment here, is rather fond of late nights'...

"Mr X supplied boys to Dolphin square on a regular basis..."

...

7."Soon after their marriage, Mr and Mrs Portillo went on holiday with Michael Brown MP, and his 'friend', a black youth who they all nicknamed Golly...

"Golly is none other than the half-caste nephew and research assistant of Lord Pitt (Baron Pitt of Hampstead)...

"His name is Derek Laud and it was he who introduced footballer Justin Fashanu to Westminster's seedier inhabitants...

"Laud has also been on holiday (to Morocco) with Lilley, Chris Chataway, and Jeffrey Archer..."

"After leaving a lunch with fergie's boyfriend, he then joined Andrew and a sailor pal at the royal home in Dorset for all sorts of fun and games.

"He was also involved somewhere in the middle of the Diana-Gilby scandal and is a frequent visitor to David Steel's flat in the now notorious Dolphin Square...

"Laud is a consultant with Ludgate Communications, a high-powered political public relations outfit, which moves in political, business, and even royal circles. In this capacity Laud has even written speeches for Prince Charles.

"Laud is a frequent visitor to Conservative Central Office where he meets Alistair Cooke, one of the original right-wing conspirators of the Maurice Cowling days in Cambridge..."
